Hello class! Today we are going to go on
a journey through the different zones of the ocean. What is a zone you might ask.
Well, a zone is a layer in the ocean. Each layer has different amounts of light and
different environments. In each layer there are also different animals because
they have certain features that make it so that they can live in that
environment. So today we are going to get in a submarine and take a little trip
through these different zones of the ocean. As we do, we are going to look at
the different animals that live in that zone and why. Let’s go! In the sunlit zone
there are the most amount of animals and plants like the dolphins, jellyfish, and
seaweed. This is because it is the warmest of the zones, and it is the only
layer with enough sunlight for plants to perform photosynthesis. If you look out
the window, you will see some sea turtles that also live in this zone. In the
twilight zone animals like the squid, the sperm whale, and the octopus live here.
There isn’t enough sunlight for plants to do photosynthesis though so they can’t
live in this zone. Moving on down to the dark zone there are bioluminescent
animals. This means they can make themselves glow in the dark. This is
because it is very very dark in this zone. Animals like the bioluminescent
jellyfish and the angler fish live here because they can produce light. The
angler fish has a light on its head. Plants aren’t found here because there
is no light. Oh look! There’s an angler fish right now! Do you see the light on
his head that allows them to see in the dark? In the abyss and trench zones,
there’s absolutely no light. Close your eyes now!
That’s how dark it is in these layers. Because of this, some fish don’t even
have eyes because it isn’t necessary. Some of these animals are the sea spider
and small squid. It’s a little too dark and cold down here I think it’s time we
go back to the classroom! Now that we are back on land I hope you learned that as
we got deeper in the ocean it got darker and colder.
There were also less animals and plants the further we went down. Now go out and
explore the world for yourself!
